Nutanix interop with existing Fiber Channel Tape library

We are thinking about going with an HCI and I was looking at my list of requirements. One is that we can use our existing Fiber channel attached Tape Library. Is this a possibility with nutanix? I am seeing conflicting reports of FC not being supported, or it only being supported if I am using VMware as a hypervisor (pass through to the machine)Can anyone shed some light on this? My end game is to use our existing Veeam infrastructure(in a vm hopefully, currently stand alone), connected to fiber channel to backup our environment to tape.

Upgrading AOS 5.1.5 to 5.20.1.1

I need to upgrade an dark site cluster from AOS 5.1.5 to 5.20.1.1.   It looks like I need to upgrade from 5.1.5 to 5.5.9.5 to 5.10.11.1 to 5.15.6 to 5.20.1.1.   Will I need to upgrade the AHV matched to each version after I upgrade the AOS?

Converting to AHV without DRS

Hi all,We recently purchased a new G7 and during this new install we converted all of our VMs to AHV using Move and we are successfully running on AOS/AHV. Working great.We now would like to convert our old 1050 with ESX/vCenter to AHV although we are hitting the DRS roadblock.We do not have a DRS license to enable this feature.We have also tried a “Trial License” and this doesn’t appear to be the best route (upgrading all kinds of vmware items just to get a “trial license enabled DRS “just to convert to AHV)My question is, now that our old cluster is decommissioned (All VMs are now on the new cluster), what would be my best approach at converting this old cluster to AHV and not having the “Convert Cluster” option hanging us up with DRS not enabled? Any input is appreciated.

Nutanix AHV Best Practices

Hello,Does anybody know where I can find the 'Nutanix AHV Best Practices', as found in the google search below, I can't for the life of me find it.Specially looking for best practices for different workloads, and that article based on the description seemed to hit the nail on the head regarding higher clock speeds for database workloads for example.i find that a lot of Google links just end up with a "Not Found or Forbidden" message.

Manually Enable RDMA nic in CVM possible?

Is it possible to enable RDMA nic manually in the CVM after manually passthrough the Mellanox network card to CVM in ESXi?It is not enable RDMA during foundation and the cluster is created.After passthrough the NICs to CVM in ESXi, I checked that the NICs are already in the lspci result but can not enable RDMA in Prism.So if it is not possible, that means if the cluster is created without RDMA enabled. there is no way to re-enable RDMA except re-foundation the cluster?

Stacked switches with AHV?

Hello,i have some questions regarding “Switch stacking”1-) Is it possible to use " 2 stacked switches " as TOR with AHV? there will be a problem if we use this configuration?2-) The best practice is to use 2 Stacked switches or 2 individual switches?We plan to use Active-Backup configuration and conect SFP to Switch1 and the other SFP to Switch2I am not a network specialist so i am not sure if both switches are stacked, and we plug 1 SFP to SW1 and the other SFP to SW2, the active passive configuration will work

IPMI port vulnerability (VNC protocol enabled)

Hi there.A security check on my nutanix clusters (8 nodes) revealed that the IPMI port on every nodes is vulnerable cause the VNC protocol is used to access them through port 5900.Issue:"...Virtual Network Computing (VNC) provides remote users with access to the system it it installed on. If this service is compromised, the user can gain complete control of the system...."Remediation:"...Remove or disable this service..."What are my options? It is possible to disable these ports without affecting the performance of the NUTANIX cluster.Thanks in advance.

Unsupported Nutanix AHV and AOS version combination installed

Hi,We used LCM to upgrade our cluster to AOS 5.20.4 and AHV-20201105.2286 on Lenovo HX7820 hardware.This combination is supported according to the Compatibility and Interoperability Matrix.However, on the Nutanix portal there now is a ‘Critical’ discovery:Cluster <removed> (UUID: <re-mo-ve-d>) is running AOS 5.20.4 and AHV-20201105.2286. This configuration may degrade functionality of new features and cause issues during cluster maintenance operations such as upgrades or cluster expansions.Install a qualified combination of AOS and AHV immediately to avoid issues that could arise from running an running an unsupported configuration.AHV-20201105.2267 is the recommended version(s) for AOS 5.20.4.If I check the C&IM, the AHV-20201105.2267 / AOS 5.20.4 combination is not supported. Does anybody know how to get this discovery resolved?

Foundation Bare metal build on Secure boot systems

I have a few systems to rebuild from baremetal. They are all secure boot enabled and to disable this I have to go onsite to change a jumper.Foundation dosen’t seem to be working which I am assuming the phoenix boot just gets skipped as its not uefi enabled. Is there a version or a process I can use to bare metal build these systems. I can easily install esxi manually if required.Just trying to avoid a trip into a covid zone to change a jumper if i can avoid it.

Try running the “set_foundation_ip_address” script on the desktopI'm running the foundation vm on the same subnet of the IPMI interfaces connected directly to an unmanaged switch, without VLANs or any other configuration. connectivity is perfect. I already reviewed all the settings and tried to reimage foundation using ESXi and AHV. Both result in the same error.Im running;Foundation_VM-5.2.2 AOS euphrates-5.20.3 LTS VMware-ESXi-7.0.1 or AHV-20201105.2244I've been trying to solve this problem for three days now, but so far I haven't found any clues.

Additional Security for AHV hosts

Many users are unaware that there are additional (beyond what is presented via the Prism user-interface) security parameters that can be employed on AHV hosts to increase the overall security of them. These security parameters are configured via Nutanix Command-Line Interface (NCLI) and include the following: Advanced Intrusion Detection Environment (AIDE) - a file and directory integrity checker High Strength Password Enforcement - configure the maximum and minimum number of characters the password must contain along with number of passwords retained in history to prevent repeated use Core Dumps - the recorded state of the working memory for a process is dumped to a file if the process ever crashes Login Banner - display a customized messages when user login to a node More information regarding these parameters, including the procedures to enable/disable them, can be found within the Hardening AHV section of the Nutanix Security Guide. Also to note, there are similar parameters

Phoenix failed to run on G3 platform

I have an old G3 block that need to be installed for a demo.And after lots of failed tries from Foundation installation, I ended up installing the node manually. But unluckily after creating phoenix iso file for AOS installation and mounting it to the node, an error occurred with message below:“Unable to match system information to layout module”Has someone seen this happened before?

diagnostic.py failed to run on ESXi 7

Hi I deploy a 3 nodes cluster with ESXi 7.0 as the hypervisor successfully on AOS 5.15.3.But when I run the diagnostic.py to check the  cluster performance. It always failed to boot the diagnostic VM. I tried 3 times and all is same. from the log, seems the CVM cannot reache the diagnostic VM when check the boot status.I login to vCenter and check that there is no IP address for this VM in the summary page. And I can login the diagnostic VM from the VM console, I can check the ip address which is 192.168.5.253, but I cannot ping 192.168.5.254 and 192.168.5.1. also cannot ping 192.168.5.253 from CVM.From this information, I think the CVM cannot reache the diagnostic VM and timeout, so the diagnostic.py will fail after timeout. Is there any idear for this test? I can run thie script successfully in ESXi 6.7.

Enable the Welcome Banner on all CVMs

If your company hardening policies require to show the welcome banner on each CVM each time a user logs in, you can disable it, make the necessary changes per our Security Guide (https://portal.nutanix.com/#/page/docs/details?targetId=Nutanix-Security-Guide-v5_16:Nutanix-Security-Guide-v5_16) and then reenable it. The following KB 8534 has the complete procedure and the commands needed to apply the banner changes in your environment.
